[android-developers] Re: How to delegate layout in an abstract ViewGroup

[Tapomay Dey]

O god, ViewStub is declared final.
Why???
I can't extend it.
How do I reuse it?

  Yeah, why not?

  Presumably, you have some logic in the code that knows the type of UI
  it's building.

  Add a ViewGroup to your layout with a known id, and have the code
  inflate the actual layout, then add it to the view group.

  Another option is to use ViewStubs in the parent layout, and call
  inflate / show on just the needed stub. This will let you specify the
  actual layout in the XML. Once a ViewStub is inflated / shown, it
  removes itself from the view hierarchy, replacing itself with the
  inflated layout.

   Is this a clean approach?

[android-developers] Re: BroadcastReceivers and orientation changes

[Hera]

Thanks Mark, I no sure about the difference between registering the
event on the activity or registering it on the application context, can
´t I pass the broadcastReceiver object thought
onRetainNonConfigurationInstance() if I made it on the activity?

Another problem would be what happends if I have another listener
(i.e. GPS location update listenes) in the same activity, with this
solution is not posible to pass 2 different objects(listeners) to the
onRetainNonConfigurationInstance, any solution?

Thank you so much.

 Rather than calling registerReceiver() on the Activity, call it on the
 Application context via getApplicationContext().registerReceiver().
 Then, pass the receiver object via onRetainNonConfigurationInstance(),
 so you unregister the same receiver when you are done.

  Hello,

  I’m having problems with BroadcastReceivers when the screen
  orientation changes.
  My Activity registers for receiving WiFi scans with a
  BroadcastReceiver and when the scan is done: (1)
  unregisterReceiver(mWifiReceiver), (2) I made some things with the
  results (by using an AsynkTask thread) and finally, when the thread is
  finished (3) the activity starts another WiFi scan and the whole
  process starts again.

  Everything works fine until a screen orientation changes occurs:

  If I do not unregisterReceiver() on the
  onRetainNonConfigurationInstance method I get this exception

  Activity myActivity has leaked IntentReceiver myActivity
  $WifiReceiver@405efad0 that was originally registered here. Are you
  missing a call to unregisterReceiver()?

  While if I unregisterReceiver(), I get this one:

  ERROR/AndroidRuntime(1490): java.lang.RuntimeException: Error
  receiving broadcast Intent { act=android.net.wifi.SCAN_RESULTS } in
  myActivity $WifiReceiver@406b4668

  Could someone tell me the correct way to manage BroadcastReceiver in
  screen orientation changes?

[android-developers] Re: Best way to support mobile app customers

[gjs]

Hi,

The best way would be in person, especially if you charge by the hour
+ expenses.

I use a website, accessible by pressing an About button within the app
+ email for semi automated bug reports where user opts to send each
email. The Android market allows links to website  email the
developer for your app.

Regards

Re: [android-developers] Re: database query

Actually if you navigate to the SQLite page on Android Developers (by simply
using the search bar and the SQL keyword), the Notepad tutorial is mentioned
there, so it is nowhere hidden, you just need to use the search and reading
skills.

2011/7/15 Indicator Veritatis mej1...@yahoo.com

 Obviously. But without being a little more specific, he will think you
 are just being rudely flippant. Especially since the title of the
 tutorial best for learning how to use the SQL database in Android does
 not even suggest that it covers SQL! I have in mind, of course, the

 basic ones),

[android-developers] Weird java.util.Timer behavior in App Widget

[cathal coffey]

Hey guys,

I have an app widget which looks like this.

public class MyWidget extends AppWidgetProvider
{
public static String ACTION_WIDGET_RECEIVER = ActionReceiverWidget;
public Timer timer = new Timer();
public int count = 0;

@Override
public void onUpdate(Context context, AppWidgetManager
appWidgetManager, int[] appWidgetIds)
{
RemoteViews remoteViews = new 
RemoteViews(context.getPackageName(),
R.layout.main);

Intent active = new Intent(context, MyWidget.class);
active.setAction(ACTION_WIDGET_RECEIVER);
active.putExtra(msg, Message for Button 1);

PendingIntent actionPendingIntent =
PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_one,
actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}

@Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER))
{
final AppWidgetManager appWidgetManager =
AppWidgetManager.getInstance(context);
final ComponentName thisWidget = new 
ComponentName(context,
MyWidget.class.getName());

count = 0;
timer.cancel();
timer.purge();

timer = new Timer();
timer.scheduleAtFixedRate(new UpdatedTimerTask(this, 
context,
appWidgetManager), 0, 1000);
}

super.onReceive(context, intent);
}
}

My UpdatedTimerTask looks like this.

public class UpdatedTimerTask extends TimerTask
{
private Context context;
private AppWidgetManager appWidgetManager;

private RemoteViews remoteViews;
private ComponentName thisWidget;

private MyWidget widget;

public UpdatedTimerTask(MyWidget widget, Context context,
AppWidgetManager appWidgetManager)
{
this.widget = widget;
this.context = context;
this.appWidgetManager = appWidgetManager;

this.remoteViews = new RemoteViews(context.getPackageName(),
R.layout.main);
this.thisWidget = new ComponentName(context, MyWidget.class);
}

@Override
public void run()
{
this.remoteViews.setTextViewText(R.id.label3, Count:  +
widget.count);
this.appWidgetManager.updateAppWidget(this.thisWidget,
this.remoteViews);
widget.count ++;
}
}

When I press Button1 on this widget its acts as I would expect. The
count gets updated every second and displays in label3.
Button1
Count: 1
Count: 2
Count: 3
etc

However when I press Button1 again I expect the count to reset to 0
and continue from there.
Whats actually happening is the two Timers are firing overlapped.

Button1
Count: 1
Count: 2
Count: 3
Button1
Count: 1
Count: 4
Count: 2
etc

Why aren't my calls to timer.cancel() and timer.purge() stopping the
first timer before replacing it?
How do I fix this issue???

Re: [android-developers] Weird java.util.Timer behavior in App Widget

[Kostya Vasilyev]

AppWidgetProvider is a subclass of BroadcastReceiver, and can (and will) be
destroyed soon after processing an event. Do not store your data or object
references there.

[android-developers] Re: 127.0.0.1 Connection refused when not connected to WiFi

[Uffe]

As I mentioned in the original post, I need to use the numeric
address.
In any case, this is not a name lookup issue. The port is definitely
open (verified with netstat), and the behaviour is consistent: WiFi
on, connection succeeds; WiFi off, connection refused.
I have tested switching the WiFi on and off without restarting the
server, and it's the same thing every time. In other words, it's not
related to the opening of the socket either; it's purely a runtime
issue which is why I'm thinking routing.

I can ping 127.0.0.1 from the device without WiFi connectivity, so
ICMP is getting through - but TCP is not.
My next step will be to write my own client too, in order to eliminate
the browser itself as the cause.

Cheers,

Hi Arun,
You need to insert images with same name is each drawable , but each image
size will change according to their screen resolution.
You have to make three images with different sizes but same name.

[android-developers] Re: alert dialog with refreshable listview

[kamiseq]

so my final solution is

A. create custom adapter based on CursorAdapter (or BaseAdapter)
B. create custom row layout in xml and inflate it in adapter
C. create AlertDialog and setItem(new CharSeq[0], null) - this will
create default list with default look and feel, without this code
listView is not initialized
D. in onPrepareDialog get ListView from dialog and set custom adapter
with new data, add click event handler which is called with item
position and id of the row(if cursor adapter was used)

when I tried creating custom dialog with scroll view and list view I
had to additionally setup layout_width and height for the dialog AFTER
it was created (so in onPrepareDialog callback) if not dialog was
quite small.

[Christine]

What exactly do you want to achieve? When the user stops your service,
they have a reason to do so, so I don't think the app should
automatically restart it.

[android-developers] Style resource parent can be specified with or without @ symbol. Bug or documentation error?

[James]

Hi,

the documentation for styles states that the parent attribute should
start with an @ but it does not seem to be mandatory.

http://developer.android.com/guide/topics/resources/style-resource.html

 parent=@[package:]style/style_to_inherit

However looking at iosched app it never uses this form but leaves out
the @

http://code.google.com/p/iosched/source/browse/android/res/values/styles.xml

 style name=Theme parent=android:style/Theme /
 style name=ListItemContainer parent=style/ListItemContainerBase /

Can someone confirm if this is a bug in implementation or
documentation?

thanks,

James

Hello Every One,
 I am trying to click  image in my application and
send it to over server
in Bytes so please help coz i need Low resolution image and send it to
server in small bytes. but my current code click image and convert it in
bytes but the image size may be big.

I use this code

parameters.setPictureFormat(PixelFormat.JPEG);
parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO);
parameters.setJpegQuality(75);
mCamera.setParameters(parameters);
mCamera.startPreview();
}
catch (Exception e) {
parameters.setPreviewSize(100, 100);
parameters.setPictureSize(20, 20);//parameters.setZoom(1);
/*Not in 1.6*/
//parameters.setZoom(0); /*Not in 1.6*/
parameters.setPictureFormat(PixelFormat.JPEG);

//parameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO); /*Not in 1.6*/

[android-developers] sendBroadcast vs ContentProvider

[sriram]

Hi ,

I have a scenario where data needs to be continously exchanged between
two applications or rather, one application acts as the data provider
and the other simply uses it.
I am thinking of two possible solutions,
1. Use the sendBroadcast() - broadcast a app-directed intent with the
specific data
2. Make the data provider application as a content provider, where all
the data is written to sqlite data base, and the first application
queries for the data after every x seconds.

Here the data is mostly String, but can be a very long String.
The frequency of updates is very frequent.
The two applications cannot be combined.. :(

I am not sure of the implications of either approach, fast vs
performance vs preferred..
What should be the suggested approach?

Thanks in advance..

4.Go

I want to give a time delay between three and Go frame which would be
a random time.

Here is my code

int d=5000;
AnimationDrawable drawable=new AnimationDrawable();
drawable.addFrame(getResources().getDrawable(R.drawable.one),
1000);
drawable.addFrame(getResources().getDrawable(R.drawable.two),
1000);
 
drawable.addFrame(getResources().getDrawable(R.drawable.three),d);
drawable.addFrame(getResources().getDrawable(R.drawable.go),d);
drawable.setOneShot(true);
iv3.setBackgroundDrawable(drawable);
drawable.start();

Where iv3 is my ImageView

And I also want to give Scale animation with frame-by-frame animation
on these images.

As I see REQUEST_ID is unique for every new request.
I need to associate REQUEST_ID of RequestPurchase with orders.
And there is no any connectivity between this id and orders, or it

Re: [android-developers] Re: alert dialog with refreshable listview

[Kostya Vasilyev]

Not sure why you need step C.

Other than that, yes, AlertDialog has a getListView method, which you 
can call from onPrepareDialog, get the adapter, and tell it about the 
new data.


-- Kostya

15.07.2011 13:44, kamiseq пишет:

so my final solution is

A. create custom adapter based on CursorAdapter (or BaseAdapter)
B. create custom row layout in xml and inflate it in adapter
C. create AlertDialog and setItem(new CharSeq[0], null) - this will
create default list with default look and feel, without this code
listView is not initialized
D. in onPrepareDialog get ListView from dialog and set custom adapter
with new data, add click event handler which is called with item
position and id of the row(if cursor adapter was used)

when I tried creating custom dialog with scroll view and list view I
had to additionally setup layout_width and height for the dialog AFTER
it was created (so in onPrepareDialog callback) if not dialog was
quite small.

 Thanks Mark, I no sure about the difference between registering the

No, because you will leak the old activity.

 Another problem would be what happends if I have another listener
 (i.e. GPS location update listenes) in the same activity, with this
 solution is not posible to pass 2 different objects(listeners) to the
 onRetainNonConfigurationInstance, any solution?

Return something that holds both the receiver and the listener. I have
used a static inner class named State for situations like that.

Not generally. If the device is in speakerphone mode, you can use
ToneGenerator for this, and I think it will work. However, you do not
have direct access to the in-call audio stream.

Re: [android-developers] sendBroadcast vs ContentProvider

[Kostya Vasilyev]

A ContentProvider doesn't have to be SQL based - you can store the data 
in memory, as long as you use a Cursor subclass that's not SQL based either.


What is a very long String?

Depending on your data size, you may want to use Messenger:

Re: [android-developers] Re: Weird java.util.Timer behavior in App Widget

[Kostya Vasilyev]

A service can get killed too, and I don't think you'd want a 
foreground-class service just to update your widget.


The usual solution is to use AlarmManager, possibly combined with a 
service, or not.


Keep in mind that updating a widget every few seconds can be a huge 
battery drain, no matter how you trigger those updates.

[android-developers] android service

[rich friedel]

You cannot hide stopping a service... all one has to do is close it from the 
settings. Also restarting a service after the user explicity shut it down will 
quickly turn users away from your application.

You can flag the service for restart after the system shuts it down by using 
the START_STICKY flag

Re: [android-developers] android service

[Perumss Naren]

Hi yanamala ,

  ya we can achieve that by Boolean flag

  the scenario  of service can destroy are:
 1. when user itself can stop the service by settings-
application settings - Running service- then your app service

2. when the mobile switch off so service can stop.

*how can we archive:*


   - Using shared preference store a Boolean value for eg: *status*
   - Once service started change that flag to true
   - If service is going to destroy then by default it will call ondestroy()
   method in service class in that change the *status *to false
   - If there is no service it will be false else it will be true
   - so from that u can check is service is running or not if running leave
   it else again start service

did i help u ?

Regards,
Perumal.N

why are you asking for index -1?  You should ask for the first row which has

Re: [android-developers] Re: Querying the max value of a column in SQLite For Android.

No, i just execute a query. The result is an cursors which has the index
-1.I think is due to a malformed query. Well i guess  i should dig more in
SQLite to find the answer. Thank you for reply.

[android-developers] Freemium Model with In-App Purchases

[polyclefsoftware]

I'm close to releasing a new iPhone/Android local multiplayer game and I'm 
looking into monetization issues. My ad revenue is still dismal this year, 
even though impressions and clicks are fairly robust. And the format of the 
game is such that I want to encourage new users to easily try the game for 
free, so I was thinking of using a freemium model where the app is free to 
download, then locks after a certain amount of gameplay and prompts the user 
to unlock the full version using in-app purchases.

I'd be interested to hear any experiences of any developers who might 
currently be using this approach. 

From a marketing/sales perspective, how well does this model work? I know 
in-app purchases for virtual goods is extremely lucrative if done well, but 
I haven't heard any experiences of the unlock-full-version model on the 
Android Market.

From a technical perspective, how easy is it for users to exploit such a 
model, e.g. uninstalling and reinstalling the app or wiping local data 
associated with the app in order to circumvent the limitations of the free 
version? Are there best practices to avoid this?

From a legal perspective, should developers (especially indie ones like me) 
be concerned about the current patent trolling and lawsuits by companies 
like Lodsys? Google still hasn't publicly commented on patent trolls 
targeting Android developers, have they?

[android-developers] Re: 127.0.0.1 Connection refused when not connected to WiFi

[Uffe]

I have now tested with a simple client, and also with Opera. It works
in both those cases.

In other words, this is not an IP stack issue but an issue with the
default browser, or possibly with the settings enforced by the
manufacturer (Samsung) or carrier (Telenor Sweden).

Either way, there is a workaround: use Opera. Good enough for me, for
now.

[android-developers] WebView Scale

[Mark]

I am having trouble manually controlling the scale of a WebView. My
Webview is loading html content with a known body size. When the app
is rotated and/or pages are loaded, I want to be able to manually
control the scale of the WebPage to control how the content is
displayed. I am currently using WebView.setInitialScale. This works
the first time I call it, but it seems that subsequent calls do not
affect the visible scale of the WebView. I am also watching the
onScaleChanged event of my WebViewClient. When the event is fired, I
often see scale values that do not reflect what I have manually set.
My html content does specify a scale value.
Any ideas?

[android-developers] How to cancel the default longclick menu on edittext

[Daniel Haywood]

Hi,

 

I am trying not get the default longclick menu (input method selections etc)
when longclicking an edittext 

 

The menu still appears after I displayed by date and timepicker dialogs.

 

I am not sure what I am doing wrong here.

 

 

  private View.OnLongClickListener MyLongClickListener = new
View.OnLongClickListener() {



@Override

public boolean onLongClick(View v) {

  if (v.getId() == R.id.textviewDayStart){

v.cancelLongPress();

mSettingStartDate = true;

showDialog(DATE_DIALOG);

  }

  if (v.getId() == R.id.textviewDayFinish){

mSettingStartDate = false;

v.cancelLongPress();

showDialog(DATE_DIALOG);

  }

  if (v.getId() == R.id.textviewTimeStart){

mSettingStartDate = true;

v.cancelLongPress();

showDialog(TIME_DIALOG);

  }

  if (v.getId() == R.id.textviewTimeFinish){

mSettingStartDate = false;

v.cancelLongPress();

showDialog(TIME_DIALOG);

  }

  return false;

}

  };

 Well, obviously, yes it is English. However, Google headquarters is

 pointing out that we HAVE no concept in our law of an official
 language, but that is a poor excuse for continuing the bad behavior.

 Besides: Google translate does an OK job on this. It would do better
 if Mr Roa would have broken the sentence up into smaller sentences,
 connecting them with the relevant pronouns.

 In particular, combining the Win7 issue and the Ubuntu issue into one
 sentence was not a good idea. And 'cualquiera' looks like it should be
 followed by another word.

 Of course, it would also help if he would SPELL in Spanish correctly!
 The word is, of course, 'después', not 'despues'! Likewise, it is no
 sé, not no se.

 Sheesh!

 But I assume what he reallymeant was something like:

  I have a problem when I start the Android emulator,
  either version 2.3.1 or any other after it is launched in Windows 7
  ['it' = Android SDK] for the latest version I have this problem,
 Linux
  Ubuntu 11.04 Android SDK  attempt to launch and I do not know if it
 is the
  connection or what but no progress but when you start to launch, and
  because of this I can not test the application I am developing.

 And yes, I am amazed that Google Translate could not translate the
 tense correctly on that last verb. The tenses are identical to English
 throughout this passage!

[android-developers] Regarding Wifi in android

[Sohan badaya]

Hi All,

I want to develop an android app that is based on Wifi. App should
always be active to receive wifi signal. From my research I have come
to know that I have to use WifiManager.WifiLock class. But this will
consume battery a lot.

Please let me know that is it only the way to get wifi signal or I
should use some other way.

Regards,
Sohan Badaya

[android-developers] Reading SQL Query row by row

[FBondarenko]

Hi there,

I'm using a large SQLite DB from which a query could return 70k+ rows.
As i understand, the query result is written to the CursorWindow, in
which the SQLiteCursor is moving freely to get values.
Since I want to limit the memoryfootprint of my query result, i want
to keep the size of the cursorwindow small.

Is it possible to get only one row at a time and explicitly step to
the next answer, even if the DB would have to be locked during this
time?

I had a look into the android-api sources and it appears to me that
the window always contains all returned rows, so it could always have
a rowcount of up to (Integer.maxValue). Only except the query would be
fired using the (at the moment) unsupported Function
public Cursor rawQuery(String, String[], int initialRead, int maxRead)

Is there another way to get the query results row by row?

Changing the SQL query or the database would be Plan C at best...

Thanks a lot!

[android-developers] How to check caching in DefaultHttpClient on Android

[Sathish]

My Android application requires to cache the response text from a web
service call using DefaultHttpClient. The cache should be valid till
the expiry time set in the Http response header.

I found similar questions but they were complaints that the
DefaultHttpClient is caching their responses. Funny I need it but
could not get working. Or there solutions suggested that are file
based.br/
http://stackoverflow.com/questions/5575181/does-android-keeps-the-
images-downloaded-from-http-in-cachebr/
http://stackoverflow.com/questions/5389524/how-to-do-image-caching-in-
androidbr/

I wrote a sample app that requests for a url on click of a button and
prints the response status and headers.

DefaultHttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
HttpResponse response;
response = client.execute(request);
System.out.println(Response status -  +
response.getStatusLine().getStatusCode());

And my GAE servlet code is,

public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
resp.setContentType(text/plain);
resp.setHeader(Expires, Wed, 11 Jul 2012 12:00:00 GMT);
resp.setHeader(Cache-Control, max-age=2592000);
resp.getWriter().println(Hi!);
}

Clicking on the button the every time gives me the status code as 200.
I expect this should be the case for the first time only.

Response status - 200
* Response Headers *
Content-Type - text/plain; charset=iso-8859-1
Expires - Wed, 11 Jul 2012 12:00:00 GMT
Cache-Control - max-age=2592000
Date - Wed, 13 Jul 2011 06:54:57 GMT
Server - Google Frontend
Transfer-Encoding - chunked

I edited the servlet and published; the client reads the latest
change.
I tested the servlet application on Chrome browser and caching works
fine.

I added the Cache-control property in the request header, but did not
get the expected result.

How do I ensure the DefaultHttpClient caches the response content and
does not send request to the server again until the expiry time?

must be editable ) and update the edited data to sqlite database.

[android-developers] Unable to send UDP msg from host to emulator.

[lb]

Hi All,

I'm running UDP application in host and emulator. My host is Fedora13
and emulator is running on same host.

The Host application receives UDP msg on 192.168.1.3:9020 from
192.168.1.3:32456 (from emulator).
Now from host I tried to send response to the emulator at
192.168.1.3:32456 but it doesn't seem to get to the emulator.

I see those two packets in wireshark and no icmp destination
unreachable. I also tried to setup redir as below:

1. Telnet localhost 5554
redir add udp:9010 udp:9099

In wireshark I see message arriving from 9010 (if I remember
correctly) and I send the response back to the same port and still
doesn't work. No errors spotted in wireshark.

Should I try telnet 192.168.1.3 5554 (emulator port) and set port
redirection.
Thanks in advance.
lb

[android-developers] Discrepancy between streaming data over localhost vs WIFI network interfaces on 3.0

[Johan Lindquist]

Hi all,

I have written a proxy server which takes a remote HLS video and
simply streams the content to the MediaPlayer (running on a Galaxy Tab
10.1 - Android 3.0.1).Whatever request the MediaPlayer makes, the
proxy mirrors onto a remote web server.

I have noticed that the MediaPlayer will not play the video correctly
(it stops, as if buffering) when using the localhost (http://localhost
URL) but while binding the server to the WIFI interface (http://
172.30.17.X URL) it happily plays it.

Has anyone ever seen a discrepancy like this when using the different
interfaces?  Any ideas on how to resolve this?  Binding to the WIFI
address is of course OK in many cases but makes things a little tricky
when on 3G.  Any suggestions and or comments on this would be
appreciated!

Cheers,

Johan

[android-developers] GPS app

[cmosser]

Hi guys,
New to Android developing, but I do have slight experience in Php and
Java, so I'm not a complete newbie. From searching online, it appears
that it is pretty trivial to get GPS coordinates out of the phone. My
question is if there is any existing interface available that would
allow me to take the GPS coordinates and retrieve, for example, what
county I'm in, what the closest lake or state park is, etc. I imagine
that it will require some kind of interface with an external map
server; ArcGis, Google maps, etc. I don't necessarily want to show a
map of the closest lake, park, etc, but rather just use the name to
extract attributes of the lake, park, etc from a separate DB. I
already have the external DB, so it's just a matter of being able to
come up with a name to reference the entries. Is this something that
can be accomplished, perhaps with the google maps API?

Thanks in advance,
Chris

If it crashes, then there will be an error, not a warning, and usually

look more closely at your LogCat output.

Re: [android-developers] Scrollviews within tabs

[Mark Murphy]

You only have one tab. Your tabs, in this design, are the immediate
children of your FrameLayout. You have one such child -- a
LinearLayout.

 Hi everybody,
 I'm building an application with 4 tabs; each tab has a scrollview
 with some textview, some spinners and 2 buttons...

 my problem is that only the current tab is displayed, when I click on
 other tabs, nothing happens... tabs don't switch and no error is
 logging

 I manage all tabs in just one activity, but I've tried to set an
 activity for each tab, with their own layout xml, but the problem was
 the same

 If I disable the scrollviews, I can see all tabs

 Thanks to anyone who will help me :)

 here my layout xml:
